#clojure – 2010-04-20

2010-04-20

00:28	jsanda	i'm trying to use clojure.contrib.string but get the following error,
00:28	jsanda	user=> (require '[clojure.contrib.string :as s])
00:28	jsanda	java.lang.VerifyError: class clojure.contrib.string$loading__5009__auto____40 overrides final method meta.()Lclojure/lang/IPersistentMap; (NO_SOURCE_FILE:0)
00:28	jsanda	my deps org.clojure/clojure "1.2.0-master-SNAPSHOT and org.clojure/clojure-contrib "1.2.0-SNAPSHOT
00:29	jsanda	i downgraded them to 1.1.0 but now i get a FileNotFoundException
00:31	jsanda	i'd like to use some of the functions in clojure.contrib.string. can anyone tell me what versions i ca/should use?
00:51	livingston	hello
00:52	livingston	well, I just learned a lot about IRC / getting verified with the nickserver, anyway...
00:52	technomancy	yeah, any chance now that we've got ops we could get that policy change?
00:52	livingston	I was trying to sort out the parallelization libaries in clojure
00:52	technomancy	*changed?
00:53	technomancy	whenever I connect as my alt nick I can never change back to "technomancy" since it says I'm banned in this channel for not being registered =(
00:54	livingston	(I don't know, there's some documentation from freenode here, that's roughly what I did, http://freenode.net/faq.shtml#nicksetup )
00:54	sexpbot	" freenode: frequently-asked questions"
00:55	livingston	so the doc on the parallelization lib say it's depricated, but then talks about how to use it, and there are parallelization functions listed on the cheat sheat ...
00:55	livingston	anyone know what's up and what API I should be looking at seriously for that?
00:56	dakrone	ack, there are so man compojure libs on clojars, how am I supposed to know which one to use?
00:56	technomancy	dakrone: my guess would be this one: http://clojars.org/compojure
00:56	sexpbot	"compojure \| Clojars"
00:57	technomancy	livingston: what's deprecated now? what's "the parallelization lib"?
00:57	dakrone	technomancy: cool, thanks
00:57	technomancy	dakrone: all "org.clojars.*" versions should be considered non-canonical
00:58	technomancy	_ato: have you tried to get any volunteers to help implement features?
00:58	livingston	the stuff that's here: http://clojure.org/other_libraries says depricated but then talks about it
00:58	dakrone	technomancy: yea, more obvious would help
00:59	technomancy	livingston: oh dang; I didn't realize the forkjoin stuff was deprecated
00:59	technomancy	I wonder what's going on there
01:00	livingston	i don't think it is, I think it's that wrapper, it's oddly worded
01:01	livingston	because then there is what's written here: http://github.com/richhickey/clojure/blob/1.1.x/changes.txt ~line 60
01:01	technomancy	oh, so maybe it's getting mainlined?
01:03	livingston	as far as I can tell, so I guess i just need to get the par branch from github, like it says, I was just wonding if anyone has done that or had any experince or docs on it.
01:05	Raynes	$example into
01:05	sexpbot	(into #{} '(a b a c d g g w)) => (w g g d c a b a)
01:29	livingston	later, thanks.
01:47	chessguy	is there some macro for evaluating an expression, but only 1 step of the evaluation, for debugging purposes?
02:09	slyphon	ok, NPE, you're on notice
02:11	slyphon	woah woah woah, you can get a NPE in a destructuring bind?
02:11	slyphon	WTF?
02:12	slyphon	how the fuck is that possible?
02:13	carkh	the question is : what the f... where you doing ?
02:13	carkh	=)
02:13	carkh	were*
02:15	slyphon	https://gist.github.com/8d9ec7b059168c1a94ae
02:15	slyphon	carkh: that
02:15	slyphon	(essentially)
02:16	carkh	ah
02:16	slyphon	i'm seriously baffled
02:17	carkh	i think you should rather look at tyhe effect of passing nil values to the URI. constructor =P
02:17	slyphon	hrm
02:17	carkh	embarassing, i know !
02:17	slyphon	but why would it say that the NPE was coming from line 1 then?
02:17	slyphon	no, i'm not embarassed, i make mistakes like that :)
02:18	carkh	we all do =)
02:18	slyphon	it's just that the traceback is telling me the wrong thing
02:18	carkh	you might want to try it at thee repl
02:18	slyphon	i'll just put in some sane defaults
02:20	slyphon	,(java.net.URI. "http" nil "localhost" 3000 "/path" nil nil)
02:20	clojurebot	#<URI http://localhost:3000/path>
02:20	slyphon	,(java.net.URI. "http" nil "localhost" nil "/path" nil nil)
02:20	clojurebot	java.lang.NullPointerException
02:20	slyphon	fuck you, Java!
02:21	carkh	ah expecting an integer it seems =P
02:21	slyphon	,(java.net.URI. "http" nil "localhost" 0 "/path" nil nil)
02:21	clojurebot	#<URI http://localhost:0/path>
02:21	slyphon	!!!
02:22	carkh	,(java.net.URI. "http" nil "localhost" 80 "/path" nil nil)
02:22	clojurebot	#<URI http://localhost:80/path>
02:22	slyphon	,(java.net.URI. "http" nil "localhost" -1 "/path" nil nil)
02:22	clojurebot	#<URI http://localhost/path>
02:22	slyphon	mother
02:22	carkh	haha that's bad
02:22	carkh	magic value !
02:26	slyphon	GAH!
02:27	slyphon	what a bunch of jerks
02:36	slyphon	carkh: thanks
02:36	slyphon	carkh: i needed someone to point out the obvious :)
02:36	carkh	=)
02:47	Licenser_	morningf
03:33	vIkSiT	hi all
03:34	vIkSiT	what resources would people recommend to learn functional data structures/algorithms using clojure?
03:34	LauJensen	Morning :)
03:35	esj	Hello all
03:35	vIkSiT	hey LauJensen, esj
03:36	vIkSiT	hrm
03:36	vIkSiT	looks like comcast is having troubles
04:08	defn	vIkSiT: id suggest just reading Programming Clojure, reading other people
04:08	defn	people's code
04:08	defn	you will start to see "imperative" style clojure vs functional style
04:08	defn	it's just time on task
04:09	defn	aww he left
04:09	LauJensen	time on task ?
04:10	defn	yeah, making stuff work
04:10	defn	writing code for fun
04:10	defn	if you don't know a lick about FP I say just jump into the mix and immerse yourself -- you start to understand how it works after you fail enough
04:11	LauJensen	I say solve Eulers 1 - 50 without any sideeffects, then you're good to go
04:11	defn	totally forgot about that -- euler was a great way to learn Clojure -- I did exactly what you say
04:11	defn	although I think I kicked the bucket at 47 :)
04:12	rys	Solve Eulers 1-50 in the same night!
04:12	LauJensen	Thats more sensible than someone like kotarak for instance, how kicked the bucket af 216 I think :)
04:12	defn	oh my god.
04:12	LauJensen	(and put the results on clojure-euler.wikispaces.com IIRC)
04:13	defn	i should go back and keep working on my euler stuff -- it's fun to watch your repository grow and grow
04:14	defn	although i can say that euler is definitely not the best way to learn all of clojure -- i knew nothing of certain real life clojure niceties living in the euler bubble
04:14	zmila	i solved almost all of the second 50 Eulers in clojure :) the first half was in javascript
04:17	defn	:)
04:22	AntonyBlakey	Trying to run autodoc on clojure git head, gives me errors like this: ./src/clj/clojure/core_deftype.clj: failed (ex = java.lang.IllegalArgumentException: Wrong number of args passed to: core$fn (core_deftype.clj:14)). which results in no documentation for things like deftype/defrecord et al.
04:22	AntonyBlakey	Anyone seen this before?
04:23	AntonyBlakey	Actually, mostly this error: failed (ex = java.lang.ClassCastException: clojure.lang.Symbol cannot be cast to clojure.lang.IPersistentVector (protocols.clj:9)).
04:23	AntonyBlakey	I'm on OS/X
04:24	Chousuke	hmhm
04:25	licoresse	I've seen it a lot, earlier ;)
04:25	AntonyBlakey	Using autodoc-0.7.0-standalone.jar
04:25	zmila	the main problem in solving Eulers in Clojure is: when I get result in REPL, then I'm lazy to copy and organize the solution pretty
04:25	AntonyBlakey	I definitely have the latest sources
04:26	Chousuke	doesn't look like there's anything weird in core_deftype.clj
04:27	Chousuke	so most likely it's an autodoc bug
04:28	AntonyBlakey	It happens on 19 source files, yet the gh-pages doc on github includes the docs for the stuff that won't generate for me, so an autodoc bug looks unlikely
04:28	Chousuke	did you try running autodoc from git?
04:29	AntonyBlakey	my next step
04:30	Chousuke	there's nothing wrong in protocols.clj either
04:31	AntonyBlakey	Nor in any of the other files.
04:32	Chousuke	zmila: :P
04:32	Chousuke	zmila: use pretty-print
04:33	Chousuke	though I suppose even better would be to use emacs and slime and write your code nicely organised right from the start :)
04:33	AntonyBlakey	Bugger, git head has the same problem. I wonder if it's an OSX specific bug.
04:34	Chousuke	I'll give it a try
04:34	AntonyBlakey	Thanks
04:35	Chousuke	what's the command you're using to build the docs?
04:35	AntonyBlakey	java -jar<path to autodoc.jar>
04:35	AntonyBlakey	In the clojure checkout
04:35	AntonyBlakey	dir
04:36	hoeck	AntonyBlakey: are you using the latest clojure? there were some breaking changes to deftype recently
04:36	AntonyBlakey	right this second git head
04:37	AntonyBlakey	And autodoc craps out on walk.clj, xml.clj, set.clj ...
04:37	Chousuke	I get it too.
04:38	AntonyBlakey	Hmm. I wonder how Tom generated the clojure.org docs then ... they include defrecord and deftype. Oh well.
04:39	Chousuke	it craps on the ns forms
04:41	AntonyBlakey	Not in core_deftype - it fails on the first defmacro
04:43	Chousuke	I wish it printed the entire stacktrace :/
04:52	Chousuke	hm. can't seem to be able to extract a stacktrace out of it
04:53	Chousuke	I suppose you need to send mail to the autodoc maintainer
04:54	AntonyBlakey	I can get a stacktrace with a source mod.
04:54	Chousuke	so what function throws the error? :/
04:55	Chousuke	or rather, what function call the function that throws the error? :P
04:55	Chousuke	calls*
04:55	AntonyBlakey	clojure.lang.Compiler.analyzeSeq(Compiler.java:4599)
04:56	Chousuke	hm. that's not the right one
04:56	AntonyBlakey	not much help. It's actually clojure not compiling the source
04:56	Chousuke	or if it is... eep
04:56	Chousuke	hm, might be a problem with the included clojure version actually
04:57	Chousuke	it's using 1.1.0 to laod 1.2.0 sources :/
04:57	Chousuke	let's try upgrading the dependencies...
04:57	AntonyBlakey	http://gist.github.com/372213
04:57	AntonyBlakey	I did that, gave a different error.
04:58	AntonyBlakey	Maybe that's the error to track down.
05:00	AntonyBlakey	a pprint error
05:00	Chousuke	right. and that's the error that you get when you try to reload clojure.core
05:05	Chousuke	it doesn't seem like --load-except-list works either :(
05:07	AntonyBlakey	I can't work out how to load the param file for clojure that comes with the autodoc src.
05:08	AntonyBlakey	It specifies not to load core.clj and parallel.clj
05:09	AntonyBlakey	Amongst other things.
05:20	Chousuke	AntonyBlakey: I have no idea either :P
06:03	vu3rdd	LauJensen: your emacs screenshot on the grand tour blog looks awesome.
06:03	vu3rdd	which color theme is that?
06:03	LauJensen	The one I mention in the preceding post: http://www.bestinclass.dk/index.php/2010/03/approaching-productivity/
06:03	sexpbot	"Approaching Productivity \| BEST IN CLASS"
06:06	vu3rdd	LauJensen: Thanks
06:06	LauJensen	vu3rdd: np :)
06:19	defn	best way to serializing a single clojure datastructure? (spit (java.io.File. data.dat) @some-ref)
06:21	bsteuber	defn: I've got (with-out-writer filename (prn obj)) - but no idea if it's better or worse
06:21	LauJensen	(spit file (prn obj))
06:22	bsteuber	,`spit
06:22	clojurebot	clojure.contrib.duck-streams/spit
06:23	LauJensen	duck-streams? A little outdated are you
06:24	unfo-	duck-streams aren't relevant anymore?
06:24	LauJensen	Not since they renamed to 'io'
06:24	unfo-	aah. kewl. ty :)
06:25	LauJensen	np :)
06:27	licoresse	someone ping me
06:27	LauJensen	We'll need an IP :)
06:28	Licenser_	failed
06:28	licoresse	:) np
06:28	licoresse	apple routers s***
06:29	licoresse	(sometimes)
06:30	LauJensen	Goes for anything made by apple IMHO
06:31	licoresse	I'm not so clever I could survive on anything different
06:32	licoresse	LauJensen: Like your post on erc
06:32	LauJensen	Great :)
06:32	licoresse	I did the same here, but using growl.el instead
06:33	licoresse	I did it for compiler notifications too
06:33	LauJensen	Its quite handy I think - Only thing I need, is that if I accidentally leave Emacs in #clojure and leave the computer, I'll probably miss any and all highlights since I left :)
06:34	licoresse	just use some enlive to scrape todays log
06:35	defn	:)
06:35	defn	enlive was so weird to me at first
06:35	defn	but it makes so much damned sense now
06:36	Licenser_	hmm do refs have something like hooks? so I get the stuff in alter?
06:36	LauJensen	,(doc add-watch)
06:36	clojurebot	"([reference key fn]); Experimental. Adds a watch function to an agent/atom/var/ref reference. The watch fn must be a fn of 4 args: a key, the reference, its old-state, its new-state. Whenever the reference's state might have been changed, any registered watches will have their functions called. The watch fn will be called synchronously, on the agent's thread if an agent, before any pending sends if agent or ref. Note that
06:37	Licenser_	ah neat
06:40	LauJensen	the watch is hooked on each datastructure, so I think you'll have to roll your own
06:40	licoresse	or just replace the add-watch fn
06:41	licoresse	no time this week
07:38	defn	class com.stuartsierra.lazytest$loading__5009__auto____3 overrides final method meta.()Lclojure/lang/IPersistentMap;
07:39	defn	ideas?
07:41	defn	it's kind of a bummer to have seen circumspec, and now lazytest, and to have followed their development for what seems like ages, not ever being able to get them to work
07:41	chessguy	is there some macro for evaluating an expression, but only 1 step of the evaluation, for debugging purposes?
07:41	hoeck	defn: someone tried to extend a final method
07:41	defn	chessguy: (macroexpand-1)?
07:42	defn	chessguy: oh i see what you mean
07:42	chessguy	yeah, not for macros
07:42	rhickey	defn: what are you doing when you get that message?
07:42	defn	(use 'com.stuartsierra.lazytest)
07:42	hoeck	chessguy: clojure-debuggers are in the works, meanwhile you can use java debuggers to do that
07:43	cemerick	defn: smells like trying to use a lib AOT-compiled for 1.1 with 1.2
07:44	defn	cemerick: that might be it -- perhaps stuart is moving lazytest to 1.2 and hasn't cleaned it all up yet
07:44	cemerick	defn: it's not a matter of cleaning anything up -- stuff that's AOT-compiled for 1.1 is not binary compatible with 1.2
07:44	defn	cemerick: i specifically saw 1.2.0-master-SNAPSHOT and 1.2.0-SNAPSHOT
07:44	chessguy	probably a code smell anyway, i need to break up these 30-line functions into smaller pieces
07:45	defn	but it might be a user error -- ill rebuild the jar -- i just found this guy hanging out in target/
07:45	cemerick	maybe, but when in doubt, load the lib from sources or a source jar instead of an AOT-compiled jar
07:46	defn	cemerick: nod -- im not familiar with mvn, i did a mvn install in the project root and found this in target/ as i said
07:47	defn	anyway, before i take up anymore of your time let me try a few things -- thanks!
07:47	cemerick	sure. FYI, AOT compilation and maven are orthogonal. It's just a matter of what's been configured to happen upon building.
07:49	bpsm	I'm having a terrible time building contrib master against clojure master.
07:49	bpsm	I posted a message about it
07:49	bpsm	http://groups.google.at/group/clojure/browse_thread/thread/1830a793986c4935?hl=de#
07:49	bpsm	any ideas?
07:50	rhickey	bpsm: the very latest? I spent the weekend and yesterday fixing that
07:50	bpsm	yea, I know...
07:50	bpsm	and I'm not seeing it on my mac anymore, but I get it consistently on my quad-core linux
07:51	rhickey	bpsm: what Java on the Linux?
07:51	bpsm	Java version: 1.6.0_10
07:51	rhickey	Sun/er, Oracle's Java?
07:52	bpsm	rhickey: sun's
07:52	rhickey	um, now Oracle has 2 Java's, aargh
07:52	defn	wait...what? 2 javas?
07:52	bozhidar	yes
07:52	bozhidar	jrockit as well
07:52	bozhidar	from BEA
07:53	Licenser_	chessguy: o.O
07:53	chouser	well, the sun one is techincally oracle's now. :-/
07:53	Licenser_	2 javas?
07:53	bozhidar	which they acquired with WebLogic...
07:53	rhickey	bpsm: you are absolutely certain you have clean builds of both Clojure and contrib, and your contrib build is using that Clojure?
07:53	chessguy	Licenser_, ?
07:53	bozhidar	Licenser_: JRockit being the second one
07:53	Licenser_	I am scared of someone having 2 javas
07:53	bpsm	rhickey: yes, I'm certain (see the reproduction script inlined in my message)
07:54	bozhidar	I hear they are planning to merge some of the features of JRockit into the standard distribution
07:54	defn	there are two javas: http://en.wikipedia.org/wiki/Java and http://en.wikipedia.org/wiki/Java_(programming_language)
07:54	sexpbot	"Java - Wikipedia, the free encyclopedia"
07:54	bpsm	rhickey: (I keep hoping I'm doing something obviously stupid, but I can't find it yet.)
07:54	bozhidar	so they might not be two for long...
07:54	bpsm	rhickey: the repo script gets fresh copies of both repositories form github and builds from those.
07:55	bozhidar	defn: there are actually more javas - the coffee, the island ... :-)
07:55	bozhidar	some people spell them jawa though...
07:55	rhickey	bpsm: what if you use commit 19dd3c593e7a29cbca514c6ab7424ff22e353cc6 of CLojure?
07:56	chessguy	anybody played around with porting any of the code from the SICP videos (http://groups.csail.mit.edu/mac/classes/6.001/abelson-sussman-lectures/) to clojure?
07:56	defn	bozhidar: my first link was to the island :)
07:56	bpsm	rhickey: 19dd3c59, the same error, the last time I tried.
07:57	defn	chessguy: yes, let me grab the link
07:57	bpsm	rhickey: will adjust the repo script accordingly to try it again...
07:57	defn	chessguy: http://sicpinclojure.com/
07:57	sexpbot	"SICP in Clojure"
07:57	bozhidar	defn: I assumed it was the Java platform - too much Java development can do that to someone's mind :-)
07:57	rhickey	bpsm: I don't see wher eyou are forcing contrib build to use a specific version of Clojure: -Dclojure.jar=...
07:57	chessguy	mm, the book is a little different from the videos
07:58	defn	chessguy: ah, my fault -- chessguy, do you want to work on it together? id like to watch those videos
07:59	bpsm	rhickey: "mvn -e -Dclojure.jar=$CLOJURE package", no?
07:59	chessguy	defn, i already started on porting code from one of the lectures
07:59	bsteuber	bpsm: I've got exactly the same problem
07:59	defn	which lecture? perhaps we could combine, fill in the gaps and such
07:59	chessguy	defn, there's a really cool generic simplification engine that they build in episode 4a. was hacking on it until like 1 am last night
08:00	bsteuber	gave up this morning to focus on other work, though
08:00	chessguy	defn, i have yet to find any code online anywhere in any language for that
08:00	chessguy	so i'm porting it directly off the slides in the video
08:00	defn	chessguy: awesome man -- ive actually downloaded all of those videos but never got around to finishing more than 1 and 2
08:00	bpsm	bsteuber: yea, I may have to move my current project back to 1.1 as contrib.json stopped working for me yesterday in connection with this problem
08:00	chouser	I just rebuilt the latest clojure and contrib on linux -- no problem at all.
08:01	defn	builds for me as well
08:01	chouser	bpsm: I didn't use -e on my mvn line
08:01	chessguy	defn, they are totally awesome. should be required watching for every single programmer
08:01	defn	i also did not use -e
08:01	bpsm	chouser: good that it works for someone.
08:01	chouser	bpsm: :-/
08:01	bpsm	chouser: I only used -e for the output it produces. i've run it without -e and gotten the same result.
08:01	chouser	this is java 1.6.0_16-b01
08:01	rhickey	bpsm: I don't grok your shell stuff well enough to see that
08:02	chessguy	defn, this simplifier is like 100 lines of code, but it would probably be 1000 in other languages, and not as expressive
08:02	chessguy	though....it's not actually working yet...
08:02	bpsm	rhicky: i've rerund my repro script for 19dd3c and see the same badness. (what am I missing?)
08:03	defn	chessguy: cant wait to get to it, im going to continue watching right now in fact :) and chessyguy, if you are interested in combining code into a consumable repo of code examples for the videos let me know -- ill start compiling as i watch
08:03	rhickey	bpsm: 19dd3c is quite neutered, it's hard for me to imagine it doing anything like what preceded or followed it
08:03	chessguy	defn, i've already committed to doing a similar port of the code in 4b for the math club in our company
08:04	rhickey	bpsm: in particular, if you are getting:
08:04	rhickey	Caused by: java.lang.NullPointerException
08:04	rhickey	at clojure.core.protocols$fn__6000$G__5996__6004.invoke(protocols.clj:11)
08:04	bpsm	rhickey: it's hard for me to imagine too
08:04	rhickey	then you are definitely not using the right version, as protocol based reduce was commented out
08:04	bsteuber	bpsm: it builds for me with -Dmaven.test.skip=true
08:04	rhickey	Caused by: java.lang.NullPointerException
08:04	rhickey	at clojure.core.protocols$fn__6000$G__5996__6004.invoke(protocols.clj:11)
08:04	rhickey	at clojure.core$reduce__6111.invoke(core.clj:4719)
08:04	chessguy	defn, yeah, i probably need to start a github repo somewhere
08:05	bsteuber	though I'm not sure if everything's fine with that build
08:05	bpsm	rhickey: no, I get teh java.lang.IllegalArgumentException: No method in multimethod '*' for dispatch value errors that come from complex-numbers
08:05	rhickey	bpsm: could you please paste/gist the full stack trace you are getting with 19dd3c593e7a ?
08:06	bpsm	rhickey: will do
08:08	defn	chessguy: chessguy http://github.com/defn/clojure-sicp
08:08	chessguy	wow
08:08	chessguy	that was fast
08:09	defn	chessguy: it's only a few commands
08:09	chessguy	yeah, i haven't really fiddle with github before
08:09	bpsm	rhickey: http://gist.github.com/372353 is partial, clojure unit tests don't write the full traces anywhere obvious.
08:10	defn	chessguy: oh -- it's pretty easy -- pm me if you need help with anything.
08:11	chessguy	defn, some of the code samples will be the same as or similar to the book, but i personally wouldn't mind re-implementing them anyway
08:11	defn	chessguy: yeah it's just a little knowledge project. who knows, it might be useful to someone at some point...
08:12	bpsm	rhickey: I'm trying to reproduce it in test-json by removing the test-complex-numbers test to see if I can get a clearer stack trace.
08:13	\|jowag\|	Hi there!
08:13	\|jowag\|	I can redirect out with binding macro, but it only works (correctly) for current thread. Is there a way to redirect out for current and all other threads created later?
08:14	chessguy	defn, am i better of /msg defn i want to clone that repository, right?
08:14	chessguy	ha
08:14	chessguy	#fail
08:14	cemerick	\|jowag\|: binding is thread-local by definition
08:15	chessguy	#morecaffeineneeded
08:16	\|jowag\|	cemerick: I know, that's why I'm finding something else to perform the redirection
08:16	Licenser_	jowag: you can use functions to do that
08:17	cemerick	\|jowag\|: rebinding out globally (or permanently swapping out System.out) is almost never a good idea. What are you fundamentally trying to do?
08:17	Licenser_	like (future x (fn [] (binding [out out] (your code))))
08:17	Licenser_	or something like that I guess
08:20	\|jowag\|	cemerick: I'm trying to remotelly control REPL without swank, so I assumed my custom server will need to redirect out so I can send it to the client :)
08:20	bpsm	rhickey: the good news is that I can't reproduce the problems with json
08:21	bpsm	rhickey: those came up toward the end of the weekend thread
08:21	bpsm	rhickey: and showed the connection to protocols
08:21	rhickey	bpsm: you have 2 completely unrelated problems, all those related to protocols are gone, this is just a multimethod thing with complex
08:22	bpsm	rhickey: ok. two problems. not related.
08:22	bpsm	rhickey: still don't unerstand why the multi-method related builds fail for me on linux and not on mac os, but i'll continue to investigate this evening. maybe i'll figure it out.
08:24	hircus	bpsm: same JVM version on both?
08:24	cemerick	\|jowag\|: The rare valid use case. Most people asking that are actually looking for a logging framework or something. :-)
08:25	bpsm	hircus: 1.6.0_10, _16, _15, _19, but all on linux
08:26	cemerick	\|jowag\|: you want alter-var-root
08:26	cemerick	,(doc alter-var-root)
08:26	clojurebot	DENIED
08:26	cemerick	hrm
08:26	_ato	bpsm: which revision of contrib are you testing with? I can't see that in the reproduce log you posted to the list
08:27	cemerick	\|jowag\|: there's a variety of remote repl servers out there already though. shrug
08:27	\|jowag\|	cemerick: Yep, I was thinking about it, but I don't know if it won't have some nasty side-effects
08:27	bpsm	_ato: you're right the mvn download output barfed all over it.
08:27	bpsm	_ato: it's af2a730fde0d8df0ab4a41153580105a36a20e7f
08:28	\|jowag\|	cemerick: well I know of swank and nailgun, any other repl servers you know of?
08:28	cemerick	\|jowag\|: if you do it wrong, it certainly will. Worth noting is that stuff written to System.out doesn't go through out, so that's something to consider.
08:28	cemerick	\|jowag\|: enclojure has one; very nice, small, easily-embeddable API
08:31	chessguy	defn, you still around?
08:31	SynrG	win 2
08:31	SynrG	buh
08:34	defn	chessguy: i am
08:34	_ato	bpsm: :/ I just ran your reproduce script on (Arch) Linux x86_64 (Sun java 2.6.0_20) and it succeeded with those revisions as well
08:37	Licenser_	sun jav 2.6?!?
08:38	_ato	typo
08:38	_ato	1
08:38	\|jowag\|	cemerick: thanks, I'm gonna look into it
08:38	Licenser_	ah okay IU was scared ther e:)
08:41	Licenser_	hi _ato by the way
08:43	_ato	aah
08:43	_ato	got it
08:43	_ato	reproduced it I mean
08:43	_ato	on a Ubuntu box with 1.6.0_15
08:43	_ato	i686
09:02	rhickey	_ato: can you please paste a stack trace?
09:06	_ato	rhickey: http://gist.github.com/372402
09:06	_ato	same as bpsm, I'm working on pulling it out of maven and trying to isolate it now
09:06	rhickey	_ato: thanks
09:12	zmila	,(reduce (fn [acc [k v]] (assoc acc v (conj (acc v) k))) {:a 1 :b 1 :c 1})
09:12	clojurebot	java.lang.ClassCastException: java.lang.Integer cannot be cast to clojure.lang.IPersistentCollection
09:13	zmila	,(reduce (fn [acc [k v]] (assoc acc v (conj (get acc v []) k))) {:a 1 :b 1 :c 1})
09:13	clojurebot	java.lang.ClassCastException: java.lang.Integer cannot be cast to clojure.lang.IPersistentCollection
09:13	zmila	,(reduce (fn [acc [k v]] (assoc acc v (conj (get acc v []) k))) {} {:a 1 :b 1 :c 1})
09:13	clojurebot	{1 [:a :b :c]}
09:14	zmila	,(reduce (fn [acc [k v]] (assoc acc v (conj (acc v) k))) {} {:a 1 :b 1 :c 2})
09:14	clojurebot	{2 (:c), 1 (:b :a)}
09:17	_ato	rhickey: seems the problem might actually be being triggered by clojure.contrib.test-load-all if I take that test out then test-complex-numbers succeeds
09:18	_ato	ah.. so it reloads everything
09:23	rhickey	_ato: so, depending on the set sort, may reload the defmethod that complex has already updated, not to be updated again
09:24	avar	I've forgotten the term used for "a language whose syntax is made up of its core datastructures" which applies to all lisps, someone help me out :)
09:24	chouser	homoiconic
09:24	avar	thanks:)
09:27	chouser	np
09:29	cemerick	some bold claims: http://blogs.perl.org/users/leon_timmermans/2010/04/why-perl-6-is-different.html
09:29	sexpbot	"Leon Timmermans at blog.perls.org: Why Perl 6 is different"
09:30	_ato	rhickey: yes, I think you're spot on
09:30	rhickey	so we need to either pull test-load-all or force it to run last
09:31	_ato	http://gist.github.com/372430
09:31	_ato	^ consistent on both machines
09:32	avar	cemerick: How funny. I was just about to reply to that:)
09:32	cemerick	avar: M-expressions, fully realized (ostensibly)?
09:33	avar	cemerick: In theory anyway.
09:37	Licenser_	cemerick: I find the rules idea pretty interesting
09:37	Licenser_	so I think it is 'too powerful' for the easy things so it will be a cool but hardly used feature
09:38	rhickey	another option is to have defmulti generate defonce
09:38	rhickey	since this is a general reloading issue
09:38	avar	Rules are used to parse Perl 6 itself. It's a very nice feature. I wish it was available in other languages, like clojure :)
09:39	AWizzArd	rhickey: if you are not too busy right now: did you see my messages to you some days ago, where I reported a bug in Cells?
09:39	cemerick	Licenser_: The syntax for rules itself looks pretty rough.
09:39	rhickey	AWizzArd: I'm not supporting cells right now
09:39	avar	Essentially perl 6 rules are just a way to move what was previously individual regex ops into subroutine calls. So you can write parsers just like you'd write classes.
09:39	rhickey	AWizzArd: got my hands full prepping for 1.2
09:39	cemerick	Most people have a hard time with sexpr macros, so more complicated metaprogramming systems are going to have even less uptake.
09:40	rhickey	AWizzArd: do you think your cells problem indicates a problem with deftype et al
09:40	rhickey	?
09:40	AWizzArd	rhickey: yes, I understand it. I just wanted to inform you about it. It's a fix of just 6 loc. It comes from deftype. (deftype Foo [a]), (:a (Foo. 10)) ==> nil
09:40	avar	cemerick: Sure, that's my worry as well. But that was always going to be the case with M-Expressions wasn't it ?:)
09:41	Licenser_	cemerick: YeaI had a really hard time to understand all the stuff even for simple things
09:41	AWizzArd	You use the field :lock in Cells, and try to access its value via (:lock some-cell). But now instead of :lock we should use (cell-sentry some-cell) instead. That's it. Shows up at 7 places in the code. Very small fix.
09:42	SynrG	win 2
09:42	Licenser_	avar: yes it is an interesting feture but the question is is it really needed?
09:43	avar	cemerick: Perl 6 (which is still evolving) does a somewhat good job of bringing you there. e.g. if you'd write (defun + (a b) (plus a b)) in lisp you'd write multi sub infix:<+>(Num $a, Num $a) { plus($a, $b) } in Perl 6. The infix:<> in turn being defined in a grammar rule that you could override
09:43	rhickey	AWizzArd: so, not a problem in deftype, but in cells.clj?
09:43	avar	Licenser_: I have no idea, for some value of "needed" :)
09:43	Licenser_	g
09:43	AWizzArd	rhickey: I would say so, yes. If deftype is not supposed to support the (:field obj) syntax anymore, then it is in cells.clj.
09:44	rhickey	AWizzArd: so, will have to wait
09:44	Licenser_	avar: what I mean is, it is cool but may of the cool things are nearly useless (or unused) in 90% of the cases
09:44	_ato	rhickey: yes, it would be nice if reloading was safe, but I can see this happening any time there's a an arrangement where one namespace "registers" something with another (whether by multimethods or some other means). I guess the only way to get around that would be to reload all the dependent namespaces transitively, which might well break other things
09:45	rhickey	_ato: there is a general issue for that transitive reloading, no progress recently. Too big to take on now
09:45	AWizzArd	rhickey: yes sure, was jfyi. I fixed it locally on my system.
09:45	avar	Licenser_: Being able to do more metaprogramming is always good. There's a lot of neat stuff being done in Perl 5 with the metaprogramming facilities it has already.
09:45	rhickey	AWizzArd: ok, I'm sure I'll trip over it next time I update :)
09:45	AWizzArd	great :-)
09:45	avar	Licenser_: Perl has bettes support for higher order functions and introspection than any other syntax-heavy language I know of, which gets used a lot in practice.
09:45	avar	anyway I'm going to stop blathering about Perl 6 in #clojure :)
09:45	Licenser_	heh
09:46	chouser	modular regex I'm sure would be very nice for certain problem domains
09:46	Licenser_	I found the regexp support in java/clojure a bit sad
09:47	avar	Modular regexes are good for anything you use regexen for, them being just strings kind of sucks for anything complex
09:47	Licenser_	I wanted to write a tokenizer and failed to find a performant way to parse the syntax since I did not find something like 'find the next matching token' I'm sure perl 6 would be great there
09:48	_ato	rhickey: not sure I entirely understand the purpose of test-load-all but if it really is just a simple sanity check to make sure all namespaces in contrib are loadable, probably just taking out :reload would do it. Or I guess removing them all with remove-ns first and then loading them again (without :reload)
09:49	rhickey	_ato: I'm more inclined towards a general fix, as people trip over this in the repl as well
09:49	rhickey	almost done
09:50	_ato	yep it has bitten me as well at the REPL. :)
09:53	chouser	avar: well, we do have #"" which is ever so slightly better than plain strings. But I agree something better should be possible.
09:53	chouser	It makes sense that perl would put that better thing at the root of the whole language, and it'll be interesting to see how that pans out. I think the right solution for Clojure will look a bit different.
09:53	qbg	Do any of the Clojure IDEs hid the javaness of exceptions?
09:56	qbg	*hide
09:59	hamza	gents what is the difference between >> and >>> bit operators in Java?
10:00	Licenser_	>> is much bigger and >>> is realy really much bigger?
10:00	_ato	hamza: http://java.sun.com/docs/books/tutorial/java/nutsandbolts/op3.html
10:00	sexpbot	"Bitwise and Bit Shift Operators (The Java™ Tutorials > Learning the Java Language > Language Basics)"
10:09	avar	cemerick: Anyway, I replied at http://blogs.perl.org/users/leon_timmermans/2010/04/why-perl-6-is-different.html
10:09	sexpbot	"Leon Timmermans at blog.perls.org: Why Perl 6 is different"
10:12	chouser	I was once pretty excited about Perl 6. Now I see mutable collections and just feel tired.
10:12	mefesto	I'm taking a first look at leiningen and was wondering if this is becoming the defacto standard build setup for clojure projects? Is this mainly for clojure only projects and maven for mixed?
10:13	chouser	mefesto: if you're comfortable with maven, I'm not sure there's much value in using lein.
10:13	mefesto	chouser: so it's a simpler alternative if you don't want to learn maven?
10:15	chouser	I shouldn't say much as I don't know much, but a log of people who are intimidated by maven seem to enjoy lein.
10:15	mefesto	ok thanks. looking forward to "the joy of clojure" btw.
10:16	hircus	mefesto: Incanter just moved from Maven to Lein, so you might want to ask there about the rationale
10:17	Chousuke	chouser: I had to code some python the other day and I found myself continuously annoyed by little things like dictionaries throwing exceptions when keys are missing and that you can't actually do "for (k, v) in dict:" ...; or that x, _ = foo fails if foo has only one element; etc...
10:17	mefesto	hircus: will do, thanks. I've been using ant this whole time and am just fed up :)
10:18	Chousuke	chouser: overall, I think python is a nice language, but the little things are suprisingly important :/
10:19	Chousuke	(I think newer versions of python might support the k,v iteration of dicts but 2.4 doesn't)
10:22	Chousuke	also I kept assuming that methods of lists return the list :P
10:22	arbscht	Chousuke: but you can k,v iterate over dict.items() iirc
10:23	Chousuke	arbscht: yeah, but I don't see why that's necessary :/
10:23	hircus	arbscht: yes; in fact you still have to do that if you want k,v iteration even in 2.6
10:23	Chousuke	I suppose it has something to do with the python philosophy of "explicit is better than implicit" but I think it fails in this case :P
10:24	hircus	Chousuke: if Python were to support multiple return values, then there is a clean way to support both for k in d: and for k,v in d:
10:25	Chousuke	hircus: well, I really wouldn't mind if only the latter case were supported, as in Clojure.
10:25	hircus	but there'd be a performance cost, presumably, in the case where you really only want the keys
10:25	hircus	I guess d.keys() already handle that
10:25	Chousuke	yes.
10:25	digash	,(deftype Foo [#^String bar])
10:26	clojurebot	DENIED
10:26	digash	[ 1] bar : Object
10:26	digash
10:26	digash	is this intentional, bug or not implemented yet?
10:30	rhickey	digash: not implemented, only primitives and Object right now
10:30	rhickey	the hint will still work, but the field type will not be limited
10:31	rhickey	i.e. the hint will avoid reflection in uses of the field
10:33	digash	got it, i guess the constructor signature will reflect that too when it is implemented
10:33	bsteuber	how do you guys organize your local javadoc?
10:35	rhickey	digash: right now it follows other hints, non-primitives are type hints but not storage or argument restrictions
10:38	digash	rhickey: in the future, is there any reason not to do an argument restrictions. I think it will make producing libraries for Java consumption easier.
10:39	rhickey	digash: it's on the todo list
10:40	rhickey	cemerick: could you please put in an issue for the ns + :gen-class thing you found the other day?
10:40	rhickey	I don't want to drop it
10:42	digash	rhickey: cool, is there an official todo list or is there a ticket I could track?
10:44	rhickey	digash: https://www.assembla.com/spaces/clojure/tickets/252-support-typed-non-primitive-fields-in-deftype
10:44	sexpbot	"#252 - Support typed non-primitive fields in deftype (New) \| Clojure \| Assembla"
10:44	cemerick	rhickey: sure, np.
10:45	rhickey	cemerick: you can put it in 1.2 milestone
10:45	cemerick	rhickey: you want a patch too, or no?
10:46	rhickey	cemerick: I got tripped up on something given the straightforward fix, then got pulled onto more pressing things, feel free to give it a shot
10:46	digash	rhickey: awesome, thank you.
10:52	cemerick	rhickey: the most straightforward fix seems to be (into {} (partition 2 options)) in gen-class -- that didn't pan out for you?
10:53	rhickey	cemerick: no, I got some error
10:53	cemerick	hrm, OK
10:54	rhickey	cemerick: when calling compile explicitly
10:54	cemerick	rhickey: as opposed to via clojure.lang.Compile, etc?
10:56	rhickey	cemerick: (compile 'the.thing.you.gave.me) was as far as I got
10:56	cemerick	ok
10:57	bsteuber	rhickey: do you confirm received CA's? Or should I just assume it arrived after like 2 weeks and start proposing patches?
10:58	rhickey	_ato or bpsm: could you please try the latest clojure in the context where you were seeing failed contrib build on complex? thanks
10:59	rhickey	bsteuber: your name will appear here: http://clojure.org/contributing. Note I don't check every week
11:00	bsteuber	rhickey: ok, thx
11:01	rhickey	cemerick: if that's working for you then I might have tripped on the other problems, since fixed
11:02	rhickey	cemerick: it should just be that simple fix
11:02	cemerick	rhickey: I'll give it a whirl later today, I'm off in faraway lands at the moment. :-)
11:03	rhickey	cemerick: I'll try again if you could point me to that gist again
11:04	cemerick	rhickey: http://paste.lisp.org/display/97911
11:05	bsteuber	rhickey, _ato, bpsm: the newest clojure commit fixes the complex number bug for me
11:06	rhickey	bsteuber: this during contrib testing phase? was it reproducible for you before the fix?
11:08	bsteuber	rhickey: yes
11:08	rhickey	bsteuber: great - thanks!
11:23	_ato	rhickey: yep, the fix worked on my machine as well
11:23	rhickey	_ato: great, thanks
11:28	shayfrendt	pop quiz of the day! why is this run-tests! method always returning a status code of 0 when run with leiningen? https://gist.github.com/31356c45d66b3594de17
11:29	shayfrendt	(since that screams n00b, feel free to kick me back to the ruby channel... :-)
11:34	Chousuke	leiningen is actually a bash script
11:34	Chousuke	maybe it just ignores the return value of java?
11:34	Chousuke	or maybe there are no failing or erroneous tests ;P
11:35	_ato	rhickey: this fix means we can no longer redefine the multimethod (eg to change the dispatch function) though, right? (well without undefining it explicitly)
11:37	_ato	I guess it has to be one or the other
11:37	djpowell	just spotted a japanese translation of stuart's book with a quirky cover
11:38	hircus	djpowell: URL?
11:39	djpowell	http://shop.tsutaya.co.jp/book/product/9784274067891/
11:39	sexpbot	"????????Clojure/???????????? - TSUTAYA ??????????? - ?"
11:39	stuartsierra	I like the cat
11:39	shayfrendt	Chousuke: hehe console output: https://gist.github.com/9b42a842ba3049a6672a I think you're right though...perhaps the bash script isn't outputting the error codes properly
11:43	hircus	stuartsierra: yah. perhaps someone should design a cat-based mascot for Clojure? (assuming Rich is not a dog-person)
11:43	fogus_	The guy who translated Stu's book has a great Scheme site: http://practical-scheme.net/
11:49	hircus	fogus_: ah, he's the Gauche guy? cool
11:50	hircus	anyone knows if in the Japanese translation, he wrote an introduction? would be interesting to read the perspective of a Scheme expert on Clojure
11:51	rhickey	_ato: there is now remove-all-methods, but yes, must undef to change the dispatch function
11:52	hircus	(at Indiana University, where the programming language faculties are Scheme heavy, Clojure tends to meet with some.. skepticism)
11:53	rhickey	hircus: no cat mascots for Clojure please
11:54	hircus	rhickey: was half tongue-in-cheek. No animal mascot at all, then?
11:54	cemerick	hrm...
11:54	cemerick	~mascot
11:54	clojurebot	the official mascot of clojure is a futuristic ninja robot
11:54	cemerick	I was never that fond of the ninja thing, though.
11:54	cemerick	rhickey: oh, seriously, their pupils are two parens! :-P
11:54	fogus_	cemerick: I was when I was 8
11:55	cemerick	ninjas are fine; ninja mascots? shrug
11:55	cemerick	"hey mister, your ninja is draggin'!"
11:56	cemerick	My cat writes half my code.
11:57	fogus_	cemerick: I vote Tom Servo... or Torgo as the official mascot
11:58	pjstadig	ninja robots have stm built in
11:58	pjstadig	cats do not
11:58	cemerick	+1 on Tom Servo :-)
11:59	stuartsierra	looks like a Dalek
11:59	danlarkin	EXTERMINATE
12:00	pjstadig	hehe Tom Servo
12:00	fogus_	Official Clojure phrase: MITCHELL!
12:00	pjstadig	i'm not sure he looks like a ninja, tho
12:03	technomancy	shayfrendt: I haven't figured out a way to pass exit codes from the project subclassloader to the main leiningen code yet
12:03	cemerick	pjstadig: what he lacks in combat skills he more than makes up for in cunning and wit.
12:03	pjstadig	the other requirement is futuristic...can't just be a ninja robot
12:04	technomancy	the security settings of the subclassloader prevent it from exiting
12:06	hircus	gtg -- bye all
12:23	chessguy	defn, ping?
12:35	cemerick	fogus_: helluva lot of hand-waving
12:36	stuartsierra	most programming language comparisons involve a lot of hand-waving
12:36	fogus_	I not even sure where to go with that post. I think I'll just stare at that XKCD comic
12:37	cemerick	Right.
12:37	cemerick	fogus_: The funny thing is, lots of these sorts of "debates" are won simply by showing up and being louder.
12:38	fogus_	I tend to prefer the fingers-in-ears-screaming-lalalalalalalala method of debate
12:40	technomancy	controversy gets readers; that's how the Internet works
12:42	fogus_	technomancy: You mean things like "Macros are the equivalent of Godwin’s Law."
12:45	_ato	I've yet to read a good article that tries to "compare" Clojure and Scala -- they all seem very superficial, and as you say more about trying to generate controversy than really do any justice to either language
12:47	stuartsierra	because no one makes serious use of both at the same time
12:47	stuartsierra	really?
12:47	fogus_	I work a lot in Scala at work.
12:48	fogus_	Used to do some monkey work in the code itself also
12:48	stuartsierra	cool
12:48	stuartsierra	so what's your take?
12:48	fogus_	Having said that. I think it's pointless to draw a comparison
12:49	stuartsierra	fogus_: heh
12:49	fogus_	You can squint and say "well this looks like that, and that looks like this other thing", but that doesn't tell you much
12:51	fogus_	As for that post, I wouldn't want to replace my macros with compiler plugins. :p
12:53	cemerick	About the only meaningful similarity is that they're both on the JVM -- which is an important connection. Other than that, just about everything is different enough to admit that they're on completely different branches of the family tree.
12:55	stuartsierra	fogus_: just gwin and bear it
12:56	fogus_	I want the head of whomever invented CSS
13:00	chouser	Any discussion of Clojure that sums up its approach to concurrency as "STM" is suspect.
13:02	shayfrendt	technomancy: thanks for the feedback - went out to lunch. i think for now we can probably just write a bash wrapper script with a regex that looks for "FAIL" in the console output :-)
13:03	slyphon	doh!
13:03	slyphon	why isn't def- public?
13:03	chouser	there's no such thing as 'def-' is there?
13:03	slyphon	no?
13:04	chouser	there's defvar- in contrib
13:04	slyphon	(def #^{:private true} blah "this is private")
13:04	slyphon	chouser: there's a def- in core
13:04	slyphon	it's just not exported
13:04	slyphon	public, whatev
13:05	chouser	are you sure?
13:05	tomoj	I can't seem to (:gen-class :main false)
13:05	tomoj	"Duplicate key: :main"
13:05	tomoj	in 1.2.0
13:05	chouser	tomoj: ha! nice.
13:05	slyphon	hrm
13:05	slyphon	chouser: damn, i thought i saw one
13:06	tomoj	similarly I can't supply a different :name
13:06	slyphon	i guess i just dreamed it
13:06	chouser	I've been wrong a lot today, so I wouldn't be surprised if you found it.
13:06	slyphon	:)
13:06	tomoj	I guess in 1.2.0, gen-class/proxy for jetty might be outdated?
13:06	redinger	technomancy: So do you have any kind of CI around your lein projects?
13:07	cemerick	tomoj: it's a known bug, I'll hopefully have a patch into rhickey today
13:07	sattvik	tomoj: I believe it's a bug in 1.2. I remember reading about it somewhere.
13:07	chouser	tomoj: I think gen-class itself is broken.
13:07	chouser	cemerick: oh, that's the one you were working on?
13:07	tomoj	yeah, but now we also have alternatives to gen-class, right?
13:08	cemerick	chouser: yes, though not much yet
13:08	cemerick	tomoj: just take out the :main false for now
13:08	chouser	nope, nothing replaces all of gen-class yet, though that will be a happy day...
13:08	tomoj	ah
13:08	sattvik	tomoj: I don't think so, not if you want to subclass a class, rather than just interfaces.
13:09	tomoj	well I think I don't even need this gen-class stuff anyway, I'm looking at http://www.deepbluelambda.org/programming/clojure/generate-your-class-and-proxy-it-too
13:09	sexpbot	" Generate your class and proxy it too : Deep Blue Lambda"
13:09	tomoj	but all I want to do is start jetty with a .war, not create my own servlets, so.. probably don't need any of this crap
13:09	sattvik	No, you don't need gen-class or proxy for that.
13:10	chouser	you're sure you don't need a named class for a .war?
13:10	cemerick	tomoj: you need at least one gen-class, as chouser suggests.
13:10	cemerick	to do a .war deployment, that is
13:11	hiredman	can't you use a deftype for that these days?
13:11	tomoj	the .war is already there
13:11	tomoj	it's not clojure stuff
13:11	sattvik	tomoj: If you already have a war file, you just need to do the embedded Jetty part.
13:11	tomoj	I just want to start jetty and point it at that war in clojure, so that clojure is in the same jvm as jetty
13:11	tomoj	sattvik: oi, I feel like I should already understand this with all the help you gave me
13:12	cemerick	hiredman: that's a good point -- deftype names should be stable now, though I don't know if they're stable as in "obvious" or stable as in "consistently generated".
13:12	tomoj	sattvik: thanks again
13:16	sattvik	tomoj: Something like this should work: http://gist.github.com/372766
13:16	tomoj	thanks, yeah, that's basically what I'm working on
13:16	tomoj	except jetty 6, so s/eclipse/mortbay/
13:17	sattvik	tomoj: Yes, that's right.
13:17	chouser	deftype produces the ununged classname all the time now, but still won't let you extend a concrete class.
13:23	cemerick	chouser: you could implement javax.servlet.Servlet, but I'll bet that'll cause issues in most containers.
13:34	slyphon	is there a slime function that switches the namespace of the repl to the one the point is currently in?
13:35	tomoj	slyphon: well, slime-repl-set-package can help
13:35	tomoj	C-c M-p
13:35	slyphon	ah
13:35	tomoj	I had one that didn't require you to accept the default and would just switch right away, but it doesn't seem to work anymore
13:35	slyphon	oh, bummer
13:36	tomoj	would be pretty simple to fix it now that I know a bit more about swank-clojure, will let you know if I do
13:36	slyphon	awesome!
13:36	slyphon	consider it a feature request :)
13:38	slyphon	tomoj: it's close enough with the default
13:38	slyphon	;)
13:39	technomancy	shayfrendt: that works for now; I'd like to find a solution to the ant subclassloader issue though
13:40	technomancy	redinger: nothing yet
13:40	shayfrendt	technomancy: roger dodger
13:40	technomancy	shayfrendt: hint hint, patches welcome =)
13:40	replaca	hmm, are docstrings on multimethods broken in master right now?
13:40	shayfrendt	technomancy: haha i knew that was comin
13:40	shayfrendt	technomancy: i'll let ya know what we come up with
13:41	technomancy	shayfrendt: probably just involves some API detective work
13:41	hiredman	replaca: what do you mean broken?
13:42	replaca	I haven't done much testing, so it might be something weird in my code, but I'm seeing no doc metadata on multimethods that are declared with docstrings
13:43	replaca	(and by "much" I mean "any") :-)
13:44	replaca	this is on files loaded with "load" if it matters
13:44	hiredman	works for me
13:44	replaca	hiredman: thanks, I'll do more detective work then
13:44	hiredman	you aren't trying to use docstrings with defmethod are you?
13:44	replaca	no, defmulti
13:45	replaca	it's through all of contrib with the autodoc engine
13:45	replaca	but maybe there's something the autodoc engine is doing that's causing the prob
13:49	hiredman	replaca: the :vars in the generated json doc for contrib have been empty for a while
13:49	slyphon	is there a way with the :require clause in ns to descend into a ns, like (:require [clojure.contrib [http [agent :as agent]]])
13:49	stuartsierra	maybe since fns got metadata?
13:50	stuartsierra	slyphon: no
13:50	slyphon	damn
13:50	hiredman	stuartsierra: docs and such still go on vars don't they?
13:50	hiredman	curl http://github.com/richhickey/clojure-contrib/raw/gh-pages/api-index.json
13:50	stuartsierra	dunns
13:50	stuartsierra	dunno
13:51	hiredman	anyway, clojurebot's ability to lookup stuff from contrib has been broken for so time
13:55	tomoj	has anyone using pmaven configured extra repositories?
14:07	tomoj	ah, translating a pom.xml with an extra repo to pom.clj just leaves it out
14:08	tomoj	guess this means it's impossible in pom.clj
14:08	tomoj	I'm beginning to like xml
14:08	fogus_	hiredman: Whoa!
14:08	fogus_	Somehow that escaped me
14:12	technomancy	back in the day we had to use proxy to add metadata to fns!
14:12	cemerick	tomoj: pmaven is quite certainly in a fetal stage. In any case, XML will be the primary project description language for some time to come, given the abundance of tools that work with it.
14:17	tomoj	"Copying 105 files to ../lib" hah
14:25	Borkdude	Can I get an Eclipse ctrl+space like autocompletion in emacs?
14:26	Borkdude	and I don't mean C-M-/ (dabbrev-completion)
14:26	technomancy	Borkdude: can you be more specific?
14:26	technomancy	err-descriptive
14:27	Borkdude	ok, I'm on the repl and I want to see all the functions/macro's that start with do
14:28	Borkdude	because I want to do something 1000 times, but I don't know dotimes
14:28	Borkdude	say
14:29	technomancy	so you're talking about non-cycling var completion?
14:29	Borkdude	What's that and how do I do it?
14:29	technomancy	I think hiredman uses something like that
14:30	tomoj	M-x slime-complete-symbol ?
14:30	Borkdude	(find-doc "do") isn't really helping
14:30	arohner	Borkdude: if you're running slime/emacs, "do" <tab> does it
14:30	tomoj	depending on what tab is bound to
14:30	Borkdude	arohner, ah good
14:30	arohner	M-x slime-indent-and-complete-symbol
14:30	tomoj	yeah, I have tab bound to that
14:30	arbscht	and if you must use find-doc, you probably want a regexp: (find-doc "^do.*")
14:31	tomoj	it takes a regexp as a string?
14:31	arohner	(find-doc #"^do\w+") does it for me
14:31	tomoj	ah
14:31	arohner	that finds "doc" and "dotimes", but doesn't find "do"
14:32	chouser	'do' isn't a Var
14:32	arohner	chouser: right, but I think the regex wouldn't catch that, even if do was a var
14:32	chouser	oh
14:32	chouser	sure
14:33	chouser	(find-doc #"^do")
14:33	Borkdude	ah find-doc with regexp is very useful, I could mention that on @cleotd
14:33	Borkdude	because it's also IDE-independent right?
14:33	chouser	arohner: oh, nm, I see what you're saying.
14:37	Borkdude	so find-doc only finds var's?
14:38	replaca	hiredman: sorry, I was in transit. Is the json index broken? or is it an issue on clojurebot's side?
14:38	chouser	Borkdude: right, not special forms.
14:38	hiredman	replaca: if you run curl, the stuff at the end where the vars with docs would be is all empty
14:39	replaca	hiredman: oh, I see!
14:40	replaca	I'll fix that up
14:40	replaca	autodoc has been going through some changes (isn't it always) so I probably broke something
14:41	hamza	is there a equivelent to read-string that will read the whole string and return it instead of one by one, (read-string "(list :A :b) (list :c :D)") returns only the first list?
14:42	ninjudd	hamza: not that i know of, but i wrote this for a project i'm working on
14:42	replaca	,(read-string (str "(do " "(list :A :b) (list :c :D)" ")"))
14:42	clojurebot	(do (list :A :b) (list :c :D))
14:42	ninjudd	(defn read-mult [str]
14:42	ninjudd	(let [r (java.io.PushbackReader. (java.io.StringReader. str))]
14:42	ninjudd	(loop [items []]
14:42	ninjudd	(try
14:42	ninjudd	(recur (conj items (read r)))
14:42	ninjudd	(catch Exception _ items)))))
14:43	replaca	,(read-string (str "[" "(list :A :b) (list :c :D)" "]"))
14:43	clojurebot	[(list :A :b) (list :c :D)]
14:44	hamza	replica ninjudd thank you both..
14:44	ninjudd	replaca: that's a good way to do it
15:06	Borkdude	any ideas for @cleotd (Clojure Example of the Day) are welcome, if you have useful snippets to share
15:06	rhickey	cemerick: fixed
15:07	cemerick	rhickey is making me look like a slacker
15:07	cemerick	;-)
15:07	cemerick	thanks
15:08	rhickey	cemerick: np
15:08	rhickey	you hadn't created an issue?
15:09	cemerick	rhickey: it's literally on my day's todo list right here. It likely would have been put in around 4-ish, after I got off this call. :-/
15:25	raek	anyone know how to make paredit insert a matching bracket, even for curlies?
15:26	technomancy	raek: you need a newer version of paredit I think
15:32	Borkdude	Is Shawn Hoover of Clojure Box sometimes in this channel?
15:32	Borkdude	I wonder why I don't have paredit included (although I find it annoying in Eclipse CC)
15:33	chouser	Borkdude: yeah, he's here sometimes.
15:34	Borkdude	Isn't paredit much like static typing? ;-)
15:35	redinger	Except useful
15:35	Borkdude	hehe
15:46	slyphon	java's URI class is completely psychotic
15:58	Intensity	Hi. I'm using counterclockwise in Eclipse (both for the first time) in an existing Java project, and I'd like to get the Java code to call Clojure code. Is anyone acquainted with Eclipse and/or CCW enough to help me with this?
16:01	kotarak	Intensity: clojure.lang.Var someClojureFn = clojure.lang.RT.var("your.namespace", "some-clojure-fn"); someClojureFn.invoke(someArgument);
16:04	Intensity	kotarak: Thanks for the information. I've seen Java code and how it can interoperate with Clojure in the way you suggest. What I'm unsure about is Eclipse, as I'd like the current Java project (built by someone else) to know how to "include" clojure.jar. I successfully added a Clojure source file to the project, but it's not yet integrated.
16:05	kotarak	Intensity: ah, ok. Sorry. Don't use eclipse.
16:07	Intensity	kotarak: Ok. I've asked in #eclipse. I may need to learn much more about it to know how to integrate a Clojure source file. I'm also completely new to it, but hope to get over the initial barrier (minimally, being able to run code like you suggest above).
16:08	kotarak	Intensity: look out for lpetit
16:08	kotarak	Intensity: he's the author of ccw and hangs out here from time to time.
16:08	Intensity	kotarak: Ok, cool. Thanks for the pointer.
16:20	tomoj	omgwtfbbq
16:20	tomoj	just got a repl into solr, hurraah
16:21	cYmen	tomoj: solr?
16:22	tomoj	cYmen: http://lucene.apache.org/solr/
16:22	sexpbot	"Welcome to Solr"
16:22	Raynes	Titles should be more useful, imo.
16:27	dakrone	I asked in #compojure, but no one seems around, can anyone tell me why url is nil in this (even though I am going to localhost:8080/parse/1)? http://gist.github.com/373003
16:27	tomoj	and I can recompile my gen-class'd plugin and see the changes without restarting solr, woohoo
16:28	chouser	tomoj: you shouldn't even have to recompile if you're just changing the implementations of your gen-class methods.
16:28	tomoj	right, I mean C-c C-k
16:28	chouser	oh ok.
16:28	tomoj	so I guess that's actually reloading
16:28	tomoj	yeah, no .class files change
16:29	tomoj	too bad there's a bunch of nasty steps to take to get into this place
16:29	tomoj	had to write a solr plugin that starts a swank server, then jar it up and embed it in solr.war along with clojure and swank-clojure
16:29	kotarak	chouser: substitute with \et for suitable Vim magic. :)
16:30	tomoj	solr gets tricked into initializing my dummy plugin which just starts swank :/
16:30	chouser	:-)
16:36	slyphon	partial confuses me
16:37	chouser	it's the next level
16:37	chouser	you'll get it. What are you looking at?
16:37	lancepantz	i haven't gotten that far yet either
16:37	slyphon	clojure.contrib.http.agent
16:37	technomancy	partial is so much fun that it can be tempting to abuse
16:37	slyphon	line 225
16:37	technomancy	along with comp and reduce
16:38	kotarak	and juxt
16:38	slyphon	i used "cons" for the first time yesterday
16:38	slyphon	that validated clojure for me
16:38	chouser	slyphon: ok, the first arg to partial is always a function
16:38	kotarak	I hardly ever use cons.
16:38	slyphon	kotarak: yeah, which is such a nice change from say sbcl
16:38	chouser	slyphon: do you see the function?
16:38	technomancy	the only time I've used cons was trying to debug a crazy macro
16:38	kotarak	,((partial str "Hello" " ") "World!")
16:38	clojurebot	"Hello World!"
16:39	slyphon	chouser: yeah, it's part of http-agent-defaults
16:40	slyphon	so buffer-bytes
16:41	chouser	heh, there are a whole lot of functions going on there.
16:41	slyphon	yeah
16:41	slyphon	i think i see what he's doin' though
16:41	slyphon	it's a way of binding stuff in a particular context
16:41	slyphon	but it won't get evaluated until you call the generated fn
16:41	slyphon	?
16:41	chouser	handle-response is a function that will get 3 args: the agent value, the result of 'partial' and opts.
16:43	chouser	handle-response (line 111) calls that second arg "handler" and invokes it with no args at all.
16:43	slyphon	ah, so partial is creating a thunk for handle-response
16:43	chouser	yes!
16:43	chouser	good!
16:43	slyphon	:D
16:43	slyphon	IT CAN BE TAUGHT!
16:44	slyphon	but you want to delay evaluation of the agent arg in that thunk until it's time? (i.e. the reply has been received)
16:44	chouser	if you know how many args partial's result will be called with (no args in this case) you can rewrite it as a fn.
16:45	slyphon	ahhh
16:45	chouser	so in this case (partial (:handler opts) a) --> (fn [] ((:handler opts) a))
16:45	slyphon	ahhh
16:45	slyphon	ok
16:45	slyphon	so it's a flexible way of doing that
16:45	chouser	right
16:46	slyphon	ok, not so hard
16:46	slyphon	:)
16:46	chouser	so more like (fn [& args] (apply (:handler opts) a args))
16:46	slyphon	ah
16:47	slyphon	i think i was expecting something more along the lines of scala's partial stuff, which i still don't really grok
16:47	slyphon	where you get the foo(blah)(wtf?)
16:47	chouser	and if you're not lost yet, you can look up the source to 'partial' and see we've essentially derived it. :-)
16:48	slyphon	hah! sweet
16:48	slyphon	ok, well, i'll have to look for a nail to hit with this hammer :)
16:48	chouser	well, scala methods can accept multiple argument lists, so ... uh ...
16:48	slyphon	yeah
16:48	slyphon	screw scala, though
16:48	slyphon	:D
16:48	slyphon	chouser: thanks!
16:48	chouser	np. welcome to the next level. :-)
16:49	slyphon	wow, only one quarter!
16:49	chouser	when you're all comfortable with partial, try it out with comp and juxt. I'm easily defeated by such bosses.
16:50	slyphon	hahaha
16:50	slyphon	hiredman blew my mind with his use of "trampoline" in callbacks
16:51	technomancy	you have to use the partial-gun to beat ReduceMan before you can defeat JuxtMan.
16:51	technomancy	haven't you played MegaMan 3?
16:51	Chousuke	:P
16:52	chouser	MetaMan?
16:53	Chousuke	It took me a while to understand how trampoline works
16:53	Chousuke	but I think I do now :/
17:06	bsteuber	,(doc juxt)
17:06	clojurebot	"([f] [f g] [f g h] [f g h & fs]); Alpha - name subject to change. Takes a set of functions and returns a fn that is the juxtaposition of those fns. The returned fn takes a variable number of args, and returns a vector containing the result of applying each fn to the args (left-to-right). ((juxt a b c) x) => [(a x) (b x) (c x)]"
17:09	tomoj	if I want to subclass an abstract java class in clojure, I'll have to use gen-class, right?
17:10	kotarak	,((juxt inc dec) 1)
17:10	clojurebot	[2 0]
17:10	kotarak	tomoj: shouldn't this also work with proxy?
17:11	tomoj	oh, thank you very much for saying that
17:11	kotarak	tomoj: well, I don't know for sure, but I think it should work.
17:11	tomoj	in other cases I need gen-class because solr will blow up if it doesn't find a .class file, but in this case, proxy is perfect because I'm returning a single-use instance of something
17:15	slyphon	gak
17:15	slyphon	& options can sometimes be a real pain
17:52	MadWombat	Hello all
17:53	MadWombat	I seem to be having trouble with Runtime. The following works fine in SLIME, but doesn't work when called from a jar (.. Runtime (getRuntime) (exec "uname"))
17:54	MadWombat	I get java.lang.IllegalArgumentException: No matching method found: exec for class java.lang.Runtime
18:01	hyp3rvigi1ant	you could download it directly from here, too, if you want: http://free.antivirus.com/hijackthis/
18:01	sexpbot	"HijackThis - Trend Micro USA"
18:01	hyp3rvigi1ant	oops
18:01	hyp3rvigi1ant	sorry
18:02	slyphon	so, if you can't await in an agent action, is there some way to "chain" agents?
18:02	slyphon	rather, chain agent actions?
18:03	sattvik	MadWombat: what do you mean by ‘called from a jar’?
18:07	MadWombat	sattvik: well, I am trying to make swank-clojure cygwin aware, when I call this expression from REPL or SLIME, it runs fine, when it gets called as part of the swank process it gives me an error
18:09	nurv	Hi.
18:12	sattvik	MadWombat: Hmm.. I don't know why it would work. You could try it without the .. macro and see if that works.
18:13	sattvik	MadWombat: I meant: "would not work"
18:16	MadWombat	sattvik: I tried every which way, with (.exec, with (. Runtime (getRuntime) and other combinations :(
18:17	Raynes	If you rebind out, how do you set it back to the default?
18:17	sattvik	MadWombat: It may be easier or perhaps even better to use (System/getProperty) or (Syste/getenv). Especially the latter since I think cygwin sets some sort of CYGWIN variable.
18:18	sattvik	Raynes: System/out, or the previously bound value?
18:19	Raynes	(binding [out System/out] ..) doesn't seem to be.
18:19	_ato	Raynes: exit the (binding ...) form? or save the original somewhere and restore it?
18:19	_ato	,(doc out)
18:19	clojurebot	"; A java.io.Writer object representing standard output for print operations. Defaults to System/out"
18:20	Raynes	(binding [out System/out] (println "lol")) => java.io.PrintStream cannot be cast to java.io.Writer
18:20	_ato	(binding [out (java.io.PrintWriter. System/out)] ...)
18:21	_ato	that doc string is somewhat misleading
18:21	Raynes	Indeed.
18:21	_ato	,(doc in)
18:21	clojurebot	"; A java.io.Reader object representing standard input for read operations. Defaults to System/in, wrapped in a LineNumberingPushbackReader"
18:21	MadWombat	sattvik: I think I partially figured it out, the call I mentioned actually works, its the other one I use that causes trouble, where I call (.. Runtime (getRuntime) (exec "cygpath" path))
18:22	sattvik	,(class out)
18:22	clojurebot	java.io.StringWriter
18:22	sattvik	Well, on my REPL it's a OutputStreamWriter.
18:22	_ato	MadWombat: from the javadoc: exec(String[] cmdarray)
18:23	_ato	you need to pass it a string array
18:23	Raynes	sattvik: In my REPL, it's a StringWriter. :p
18:23	Raynes	Cause of swank, I guess.
18:24	sattvik	MadWombat: You can do (exec (into-array "cygpath" path))
18:28	sattvik	Raynes: Checking the Clojure source: out is set in RT.java to new OutputStreamWriter(System.out). So, like _ato said, exit the (binding …) or save and restore the original.
18:31	MadWombat	sattvik: nah, I just use (str "cygpath " path)
18:32	MadWombat	I have a rather stupid question, how do I assign value to a function argument? That is if I have (defn f [x] (how do I change value of x from here?))
18:32	_ato	MadWombat: that might break on paths that have spaces in them though
18:33	MadWombat	_ato: correct, I will fix that
18:35	_ato	MadWombat: by "assign" are you talking about default arguments? (defn f ([] (f "something")) ([x] ...))
18:35	_ato	so (f) is then equivalent to (f "something")
18:36	MadWombat	_ato: no, I need to change the actual value passed into the function
18:36	_ato	either I'm misunderstanding what you mean or that's not possible in Clojure
18:37	_ato	there's shadowing: (defn f [x] (let [x (inc x)] ...))
18:37	MadWombat	_ato: in this case, I have a file name passed into a compile function and I need to check if I am under cygwin and convert the file name if I am. There is a bit of stuff done with the file, so I don't want to enclose the whole thing in the if form or something, I just want to change the file name in place
18:39	_ato	so I think shadowing is what you want... (defn f [path] (let [path (cygwin-path path)] ... normal body ... ))
18:43	scottj	MadWombat: in clojure (and I believe many other functional PLs) you don't reassign "variable names"
18:43	MadWombat	_ato: thank, seems like it does what I want
18:44	MadWombat	scottj: a form, by any other name...
18:54	heauxbag	what's a good starting point for someone interested in learning clojure? fairly experienced programming background but not much functional/lisp experience
18:56	technomancy	~peepcode
18:56	clojurebot	peepcode is a commercial screencast series; see the Clojure one at http://peepcode.com/products/functional-programming-with-clojure by technomancy
18:57	sattvik	heauxbag: There is the Clojure 101 course starting in a few days: http://rubylearning.com/blog/2010/03/09/clojure-101-a-new-course/
18:57	sexpbot	"Clojure 101: A New Course"
18:57	technomancy	the prags' book is quite good too
18:57	cemerick	there's also the full disclojure series
18:57	cemerick	The Joy of Clojure MEAP has been excellent so far.
18:58	heauxbag	technomancy: actually got the peepcode screencast, glad people recommend it
18:58	cemerick	heauxbag: Mark Volkmann's long tutorial is really fantastic. Very gentle intro: http://java.ociweb.com/mark/clojure/
18:58	sexpbot	"Mark Volkmann's Clojure Page"
18:58	technomancy	cools
18:58	cemerick	hrm, http://java.ociweb.com/mark/clojure/article.html is the actual tutorial
18:58	sexpbot	" Object Computing, Inc. - Java News Brief - March 2009"
19:02	scottj	heauxbag: I think rich's screencasts are superb
19:02	scottj	recorded talks showing him code rather
19:28	MadWombat	is there an HTML parser for clojure?
19:30	scottj	there's java's tagsoup and enlive
19:31	MadWombat	scottj: how do I make lein recognize them as deps?
19:32	scottj	http://clojars.org/enlive
19:32	sexpbot	"enlive \| Clojars"
19:33	scottj	add the lein line to project.clj. for jars I think you install them to maven (some maven commands will print out the command line in their errors) and then referencing it in project.clj also
19:34	nurv	http://github.com/nathell/clj-tagsoup
19:35	scottj	I guess tagsoup is in clojars as well so you don't have to install manually with maven
19:35	MadWombat	how do I install an arbitrary jar into a maven repo so I can use it with lein?
19:36	MadWombat	scottj: enlive looks promising
19:36	technomancy	MadWombat: if you edit your project.clj to reference it and then run "lein deps", the error message will include instructions of how to install it
19:36	technomancy	locally anyway
19:36	MadWombat	technomancy: thanks
19:37	MadWombat	technomancy: sorry about erronious pull request earlier
19:37	scottj	MadWombat: the line you're looking for is like this: mvn install:install-file -DgroupId=com.google.appengine -DartifactId=appengine-api-1.0-sdk -Dversion=1.3.0 -Dpackaging=jar -Dfile=appengine-api-1.0-sdk-1.3.0.jar
19:37	MadWombat	scottj: heh
19:37	MadWombat	scottj: thanks
19:37	MadWombat	scary
19:37	technomancy	np
19:38	scottj	technomancy: what's the argument against having a dir in the project that lein will look for jars instead of going to maven dir?
19:39	scottj	is it the lack of groupid and version?
19:39	technomancy	scottj: you mean checking jars into git?
19:39	technomancy	git is abysmally bad at tracking binary files
19:40	technomancy	every time you upgrade a dependency, the diff will include a removal of the entire old jar plus a re-add of the new jar
19:40	technomancy	pretty soon a fresh clone of your project takes twenty minutes
19:41	scottj	technomancy: nothing to do w/ git, I mean having a dir like lib that has jars that get included on classpath but they don't get deleted w/ lein clean
19:42	technomancy	so each developer is responsible for tracking down all the deps and putting them in the right place manually?
19:42	technomancy	it's doable, just tedious
19:42	scottj	well, you end up doing worse than that if you have to install to local maven repo
19:43	technomancy	yeah, a local maven repo is only a temporary solution
19:44	technomancy	once it's in a local repo, it's easy to rsync out somewhere so you can share it
19:47	scottj	I guess the argument against having a jars dir that's included on cp and not deleted like lib, that you'd use for jars that aren't in public repos, is that ppl should learn to use mvn local install, it's not too hard :)
19:47	technomancy	even a remote mvn server is not that tricky either
19:48	technomancy	it'd be cool if someone documented how to set up a private clojars instance
19:50	cemerick	technomancy: can nexus, artifactory, etc., not serve as a lein deploy target?
19:50	technomancy	cemerick: good question. I haven't looked into it.
19:51	technomancy	my gut tells me hudson would be the quickest way to get going, but there could be better options.
19:51	cemerick	the free version of nexus is absurdly full-featured, and dead-simple to deploy.
19:52	cemerick	hudson-as-a-repo is a bit of a hack -- in particular, the fact that it doesn't prevent release redeployments is irksome
19:54	technomancy	it's worked great for us in our narrow use case, but I could see how that'd be a problem
19:54	technomancy	I am interested in alternate clojars installations for other reasons though; I think down the line third-party mirrors will be come a necessity
19:55	technomancy	given an optimistic projection of Clojure's growth
19:56	cemerick	I'd hope that we could start getting popular projects rolling into central. That would necessitate something like artifactory or nexus, as central is moving quickly away from ssh/scp/rsync-based mirroring.
19:58	cemerick	you mean syncing with central?
19:58	technomancy	yeah, making it easy to sync from clojars to central
19:59	cemerick	it's apparently a piece of cake if you're not trying to sync with them via rsync...even easier if you're signing the artifacts.
19:59	chessguy	'evening
19:59	cemerick	@talios has gone through this for clojure-maven-plugin, sounds like the process has been simplified and expedited quite a bit
20:00	chessguy	anybody care to help me debug an algebraic simplifier?
20:02	cemerick	technomancy: even easier, sonatype is apparently providing nexus hosting for open source projects http://www.sonatype.com/people/2009/06/publishing-your-artifacts-to-the-central-maven-repository/
20:02	sexpbot	"Sonatype Blog » Publishing Your Artifacts to the Central Maven Repository"
20:05	technomancy	if it can match "scp pom.xml foo.jar clojars@clojars.org:" for ease-of-use, I'm all for it.
20:06	Tordek	hi, what's the - in "(defn -name...)"?
20:08	sattvik	Tordek: Generally, there is nothing special about it. Specifically, it is often the default prefix of functions that are implementing Java methods that are being generated using gen-class.
20:08	remleduff	There's an awful lot of value of being able to go to clojars and browse and only get clojure artifacts, I'd hate to lose that if the community moved to a nexus repository
20:08	Tordek	thanks
20:40	defn	another amazingly awesome post by nakkaya: http://nakkaya.com/2010/04/20/fractals-in-clojure-newton-fractal/

21:08	chessguy	hey defn
21:31	MadWombat	I need to parse a javascript array definition, so I think, I need a basic token parser. Is there a library I can use or a sample parser I can take a look at?
21:32	dakrone	MadWombat: you could give http://github.com/jrockway a shot
21:32	dakrone	err
21:32	dakrone	http://github.com/joshua-choi/fnparse
21:33	dakrone	wrong link
21:34	chessguy	did i get banned?
21:34	_ato	,(read-json "[1, \"hello\", 3]")
21:34	clojurebot	[1 "hello" 3]
21:34	_ato	MadWombat: ^ if you just mean parsing a JSON array
21:34	dakrone	chessguy: err, no? you're in here now
21:34	_ato	clojure.contrb.json.read
21:35	chessguy	yeah, weird, i got a strange message from freenode saying i'd been banned
21:35	_ato	clojure.contrib.json.read *
21:35	chessguy	defn, you around?
21:36	tomoj	_ato: how'd you know read-json was available?
21:36	MadWombat	_ato: worth a try :)
21:37	lancepantz	clj-json is much much faster than clojure.contrib.json
21:37	MadWombat	_ato: I need to extract an array from a javascript file, I use regex to separate the array definition from the rest of the code and now I need to parse the array itself
21:37	lancepantz	fwiw
21:37	_ato	tomoj: /msg clojurebot ,(read-json "[1, \"hello\", 3]")
21:37	tomoj	oh, heh
21:43	hiredman	clojurebot also has danlarkin's clojure-json stuff
21:50	chessguy	man, i sure would love it if someone could take a look at this simplifier code and help me debug it: http://ideone.com/VlRwu

21:51	chessguy	(as an aside, the syntax-coloring on that site for clojure sucks)
22:31	wlangstroth	It seems that Scala is losing popularity on Github: http://github.com/languages/Scala
22:32	wlangstroth	Clojure is still #18, and at #19 ... Common Lisp.
22:41	joshua-choi	I've got a question. Before deftype switched from factory function (A x y) vars to class constructors (A. x y), I often used namespace aliases with my deftypes' factory functions (require [something :as s]) (s/A x y).
22:42	joshua-choi	Now, I seem to be unable to do that with the new constructors.
22:42	joshua-choi	Is it possible to use namespace aliases with the deftype constructors at all? Or do I have to use import from now on?
22:50	hiredman	joshua-choi: if you switch to defrecord or make your own factory function
22:51	joshua-choi	hiredman: Actually, I'm using defrecord; I'm still running into the same problem. I didn't mention it just for conciseness
22:51	joshua-choi	A factory method is probably my best bet, but it's unfortunate...What did you mean by defrecord, though? Does it do something different in this case?
22:52	hiredman	the same problem as in no factory functions?
22:52	joshua-choi	Yeah.
22:52	hiredman	huh
22:52	joshua-choi	Does defrecord create factory methods?
22:52	hiredman	I had thought defrecord was supposed to supply those
22:52	joshua-choi	Hmm, actually, hang on...
22:53	hiredman	factory functions
22:53	joshua-choi	hiredman: No, defrecord doesn't seem to create factory functions for me.
22:53	joshua-choi	Does it for you, in the latest Clojure?
22:54	hiredman	let me grab the latest
22:55	hiredman	actually the docstring for defrecord doesn't mention factory fns
22:56	hiredman	that is some what worrying, I thought the point was to have a level of indirection between you can the class
22:57	joshua-choi	hiredman: The removal was a pretty new change; did you know about it? (I found out two days ago :( )
22:58	hiredman	I knew it was removed for deftype
22:58	remleduff	You can't have a factory function that has the name of the Class, because the Class name is now supposed to be stable, and they'd conflict
22:58	hiredman	remleduff: even if you re-defrecord?
22:59	joshua-choi	remleduff: Right. But is there a way to use namespace aliases still? Or must I (import ...) now?
22:59	hiredman	I haven't really been following it that much, I mean, I'm simple, I just use functions maps and seqs with a set here and there
23:00	remleduff	I hadn't encountered that, I guess you'd have to import. You also can't (map RecordType [values]) anymore either, there were a handful of cases Rich was trying to decide whether they were important enough to support was my impression. He'd talked about something like RecordType/create I think
23:04	remleduff	http://clojure-log.n01se.net/date/2010-04-15.html#07:55
23:04	sexpbot	"#clojure log - Apr 15 2010"
23:04	joshua-choi	remleduff: How long ago did Rich mention RecordType/create?
23:04	remleduff	Was just searching for it :)
23:04	joshua-choi	Wow, at the same time. :)
23:11	remleduff	I'm surprised no one has run into that before, I guess most people don't use records from a different namespace than the one they define them in? Or else they didn't alias the namespace
23:12	joshua-choi	I'm surprised too, though
23:14	joshua-choi	Ah, someone did ask it, on 2010-04-15 10:46.
23:17	remleduff	Hmm, that just makes the ns macro even more complicated (require and use are for clojure stuff, import is for java stuff -- except import is also for records and types)
23:19	joshua-choi	I know. I hope Mr. Hickey will figure out something about the factory methods, or at least a definite no.
23:19	joshua-choi	No pressure though
